We're open-sourcing Asimov Legs, a bipedal robotic system. It's a complete leg design with 6 DOF per leg, RSU ankle architecture, passive toe joints. Built with off-the-shelf components and compatible with MJF 3D printing. What we're open-sourcing & sharing: - Full mechanical

You can now build humanoid legs following Asimov's design. The actuators list, design files, and XML for training are available. Technical report coming today. Training guide soon after.

Asimov is an open-source & modular humanoid. We're finalizing the full body by March 2026 and open-sourcing each part as it's ready.

The complete legs subsystem costs just over $10k all-in. R&D for the last 100 days came under $30k, which includes hangar space, tooling, and replacement parts. These costs spread across the whole body development, not just the legs.

Asimov built humanoid robot legs in 100 days and open sourced the designs yesterday. Check it out!

Asimov Legs, a 1.2m-tall bipedal system, is now open-source. It features 12 DOF, an RSU ankle for pitch/roll, and passive articulated toes for better traction. The design uses 3D printing and off-the-shelf parts.

Love the detailed writeup. The modular design is a particularly nice note as it will hopefully making servicing/keeping a robot operational much easier.

This day changed everything. For the first time ever, Asimov walked the same way in reality as in simulation. We closed the sim2real gap. We're writing about how we got here.

We're sharing all materials, reasoning behind choices, and learnings for everybody to build on, improve, and shape. Feel free to follow on X & subscribe to the newsletter: news.asimov.inc

Day 130 of building Asimov, an open-source humanoid.

This is an amazing post, it demonstrates everything about humanoids: 1.) break down your hardware into sub tests. 2.) sim2real gap closure is hard and important. 3.) Estops, have them, but press them only when you need to. 4.) the robot wrangler moves like the humanoid,

We're starting upper body assembly. The full humanoid is coming together.

We're using MuJoCo, and you can get the simulation model too. It's open-source: github.com/asimovinc/asim…
